材などに広く用いられている。Detailed Description of the Invention The present invention relates to an amorphous gold steel strip and a method for manufacturing the same.-1 Amorphous metal strips have ferromagnetic properties and also have a uniform composition that cannot be obtained from crystalline metal strips. It is widely used as a furnace material for electromagnetic filters because it can produce an alloy pot with the same composition.
従来この非晶質金属帯は、溶湯急冷法によって製造され
ている。溶湯急冷法は第1図に示すように、金JA(純

持しつつ、ノズル3から回転するロール4の表面に噴出
し、急冷して金属帯5どするものである。Conventionally, this amorphous metal strip has been manufactured by a molten metal quenching method. As shown in Figure 1, in the molten metal quenching method, gold JA (pure metal or alloy) molten metal 1 is maintained at an appropriate temperature with a heater 2, and is jetted from a nozzle 3 onto the surface of a rotating roll 4 to rapidly cool it. This is to remove the metal band 5.
ところが、この従来の溶湯急冷法では平坦な非・品質金
属帯しか得ることができなかった。即ち、金属帯の幅方
向の断面を示す第2図において、口 ゛−ルに接触して
急冷きれた面5Aは平らな面とな 。However, with this conventional molten metal quenching method, only a flat, non-quality metal strip could be obtained. That is, in FIG. 2, which shows a cross section of the metal strip in the width direction, the surface 5A that has come into contact with the mouth and is rapidly cooled is a flat surface.

平坦なものとなっている。第2図Aは金属帯幅の広い場
合、第2図Bは金属帯幅の狭い場合である。The surface 5B solidified without contacting the roll becomes a slightly rounded surface due to the surface tension of the molten metal, and is flat as a whole. FIG. 2A shows the case where the metal band width is wide, and FIG. 2B shows the case where the metal band width is narrow.

kなるなどの問題があった。特にフィルターの捕捉性能
を高めるためにリボン幅を小さくした場合にはこのよう
な問題が発生しやすかった。When such a flat amorphous metal strip is used as a member of an electromagnetic filter, when stress is applied to the fluid, the surfaces of adjacent ribbons overlap, causing the metal strip to collapse inside the filter. There were problems such as uneven distribution or deformation and easy breakage. Such problems are particularly likely to occur when the ribbon width is reduced in order to improve the filter's capture performance.
本発明の目的は、このような従来技術の問題点門解消し
た非晶質金属帯及びその製造方法を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an amorphous metal strip and a method for manufacturing the same, which eliminates the problems of the prior art.
本発明は、実質的に連婢した非平坦面を有する帯状であ
る非晶質金属帯に関し、また溶湯急冷法で非晶質金属帯
を製造するに際し、ロール表面に凹凸を設けることによ
って、非平坦状の非晶質金属帯を製造する方法に関する
ものである。The present invention relates to a band-shaped amorphous metal strip having substantially continuous non-flat surfaces, and also relates to a non-crystalline metal strip that is formed by providing irregularities on the roll surface when producing the amorphous metal strip by a molten metal quenching method. The present invention relates to a method of manufacturing a flat amorphous metal strip.
本発明においては用いられる金属原料は特に限定される
ものではなく純金属の他、各種の合金をも原料とするこ
とができる。The metal raw materials used in the present invention are not particularly limited, and in addition to pure metals, various alloys can also be used as raw materials.
非平坦状の非晶質金属帯を電磁フィルターに用いた場合
には次のような優れた効果が得られる。When a non-flat amorphous metal strip is used in an electromagnetic filter, the following excellent effects can be obtained.
第1に磁性物質の捕捉性能において優れている。First, it is excellent in its ability to capture magnetic substances.
即ち、電磁フィルターは被処理流体中の物質を磁力作用
によって捕捉するものであるが、平坦な非晶質金属帯の
場合、磁性物質を磁気的に捕捉する−ための高勾配磁束
点が金属帯の側端而のみであるのに対し、非平坦状の金
属帯の場合は、側端面に加えて各頂点が高勾配の磁束を
有する捕捉点となり、捕捉点の量が著しく増大するから
である。In other words, an electromagnetic filter traps substances in the fluid to be treated using magnetic force, but in the case of a flat amorphous metal strip, the high gradient magnetic flux points for magnetically trapping magnetic substances are located in the metal strip. In contrast, in the case of a non-flat metal strip, in addition to the side edges, each vertex becomes a trapping point with a high gradient magnetic flux, and the amount of trapping points increases significantly. .
第2に、金属帯が非平坦状であり、頂部と谷部を有する
から該金14帯の面が重なりにくくなり、金属帯が偏在
することがなくなシ、フィルターの通水抵抗が減少する
。Second, since the metal strips are non-flat and have tops and valleys, the surfaces of the gold 14 strips are less likely to overlap, preventing the metal strips from being unevenly distributed, and reducing the water flow resistance of the filter. .
第3に、従ってフィルターの通過水を増加させることが
できるから、第1の捕捉性能の増加と相まって、電磁フ
ィルターの処理能力を増大させることができる。Thirdly, since the amount of water passing through the filter can therefore be increased, combined with the increase in the first capture performance, the throughput of the electromagnetic filter can be increased.
第4に、金属帯が流体から応力を受けても変形する程度
が小さくなシ、変形に伴う疲労が小さく′ なシ、金
属帯の寿命も長くなる。Fourthly, even if the metal band receives stress from the fluid, the degree of deformation is small, the fatigue associated with the deformation is small, and the life of the metal band is extended.
また、本発明の非晶質金属帯を熱交換用部材として用い
た場合には、単位長さ当りの表面積が大きくなることか
ら、熱交換性が向上する。Further, when the amorphous metal strip of the present invention is used as a heat exchange member, the surface area per unit length is increased, so that heat exchange performance is improved.
さらに、本発明の非晶質金属帯を各種化学反応の触媒に
用いた場合゛にも、同様に単位長さ当りの表1面積が大
きいことから反応速1度を増大させることが可能となる
。Furthermore, when the amorphous metal strip of the present invention is used as a catalyst for various chemical reactions, it is possible to increase the reaction rate by 1 degree because the surface area per unit length is large. .
また本発明の製造方法によれば、溶湯は凹凸を有するロ
ールの表面に沿って凝固するから、ロール表面の形状に
応じた非平坦状の非晶質金属帯となる。Furthermore, according to the manufacturing method of the present invention, the molten metal solidifies along the uneven surface of the roll, resulting in a non-flat amorphous metal band corresponding to the shape of the roll surface.
本発明において、ロール表面に凹凸を設ける手段として
は、例えば切削あるいは鋭敏な砥石を用いて刻設する方
法等が採用できる。In the present invention, as a means for providing unevenness on the roll surface, for example, cutting or engraving using a sharp grindstone can be employed.
またこの凹凸の形状も任意のものとすることができる。Further, the shape of the unevenness can also be arbitrary.
例えば、ロール表面に溝を多数段ければ得られる金属帯
も、多数の摺曲を有するよ、うになる。For example, a metal strip obtained by forming many grooves on the surface of a roll will also have many sliding curvatures.
しかしてとの′溝の形状は、任意のものとすることがで
き、第3図A−Dに示すようにV字状の溝を連続的に(
第3図A)、適当な間隔をおいて(第3図B)、あるい
は台形の溝(第3図C)、正弦波形の溝(第3図D)な
どのようにすることこのような溝形状としたときの得ら
れる金属帯 ゛の長手方向の断面形状を第4図A−D
に示す。第4図のA−Dは第3図のA−Dにそれぞれ対
応するものである。However, the shape of the groove can be arbitrary, and as shown in FIG. 3A-D, the V-shaped groove is continuously formed (
Figure 3A), at appropriate intervals (Figure 3B), trapezoidal grooves (Figure 3C), sinusoidal grooves (Figure 3D), etc. The cross-sectional shape in the longitudinal direction of the metal strip obtained when shaped is shown in Figures 4A-D.
Shown below. A to D in FIG. 4 correspond to A to D in FIG. 3, respectively.
特に本発明においては金属帯の降伏は、長手方向に正弦
波形状に摺曲し、悲平坦状となっているものが好ましい
。これは、7字形状や台形状のものは、i部が折れ曲っ
た形状のものであるから、該、頂部に応力集中が生じ材
料の疲労が蓄積しやすいが、正弦波形状にするとこのよ
うな折れ曲シ部がなく、応力集中がほとんど無くなるか
らである。In particular, in the present invention, it is preferable that the metal band yields in a sinusoidal shape in the longitudinal direction and is flat. This is because the shape of a figure 7 or trapezoid has a bent i section, so stress concentration occurs at the top and fatigue of the material tends to accumulate, but when it is made into a sine wave shape, this happens. This is because there are no bends and stress concentration is almost eliminated.

。 □以下実施例について説明する。According to the manufacturing method of the present invention, the effect of surface tension on the free solidification surface when the molten metal contacts the rolls and rapidly solidifies is reduced, so that the thickness of the amorphous metal strip becomes uniform. be. Further, the present invention can easily produce a non-flat amorphous metal strip because it is sufficient to provide irregularities on the roll surface of a production apparatus using a conventional molten metal quenching method. □Examples will be explained below.
